A strong, flexible, clear, waterproof glue to seal HID lights?

[DarrenSV650S]

:-k

I need to seal up my HID's to make then watertight but it will be seen so needs to stay clear and not react to sunlight and weathering. It needs to flex slightly too, so can't be brittle like superglue.
Any recommendations on what to use? Would some kind of resin do the job?

[slinky]

could try an empoxy resin or maybe try and find a gasket of some description?

[TamSV]

Would a decent clear silicone sealant do the job? You can get stuff that's meant to be non-yellowing/UV resistant etc.

[Nobbylad]

Silicone or PU?

[DarrenSV650S]

Yeh I'm thinking resin might be good. A gasket wouldn't work just because it needs to seal up thin gaps that I can't separate. I think silicone would be too thick. It needs to go in quite a narrow V shape gap

What's PU?

[Bibio]

depends how much you need to use. if its a small amount then i would recommend UniBond Extreme power glue. it stays quite flexible but is stroooong. takes ages to set though.

Have you used it on plastics? You know sometimes when you use superglue it leaves white powdery marks around the repair. Can't have that =; :)

well i stuck a cable tie base to a strip of dirty metal and the base stayed black around the edges and the glue is still clear. its rock solid but i guess if i took a hammer or chisel to it it would come off. £5 a 20g tube though.

[Bibio]

its a bit like a silicon though as its quite thick.

[DarrenSV650S]

Might give that a try

[Specialone]

I would use a good exterior clear silicone, sticks like sh1te, flexible and will last for ages.

You can also put Silicone in a Syringe and "pipe" it into quite small places . I also use a Silicone Primer which makes it stick like nobody`s business .... what for ? I cannot discuss , but trust me , it`s good enough for the Military :)

[DarrenSV650S]

Forgot to say it needs to be heat resistant too! :)

[xXBADGERXx]

Not a problem ;)

[DarrenSV650S]

Something like this then?

Personally id go with a good branded building silicone, what youve gotta watch for is the silicone companies sell a lot of the same silicone in different packages and market it differently, but underneath a lot of it is the same but they charge more for it.
The one youve linked to would work fine im sure, but £10 for a tube of silicone is way too expensive.

[DarrenSV650S]

Can you recommend one?

[Specialone]

Any of the good brands will perform well tbh, I can't recommend one in particular, especially for what you wanna use it for but unibond is probably brand I use the most.
I use bond-it brand a lot as well, they are a lot cheaper but very good.

I go through 100's of all types every year tbh, never really had a bad one but never used one in a headlight ;)

Try screwfix.com, they have loads in there.

[DarrenSV650S]

Ok I'm thinking this (http://www.screwfix.com/p/no-nonsense-glazing-silicone-clear-310ml/81431) and these (http://cgi.ebay.co.uk/10ML-SYRINGES-LONG-NEEDLES-SET-4-/380277639614?pt=UK_CamerasPhoto_Printing_PrinterIn kCatridges_JN&hash=item588a5049be) :)

[Specialone]

Shame your not local, I've got some glazing silicone you could've had, not worth posting tbh.
The no nonsense stuff ain't bad for the money.

Hot glue gun or silicone

I use this stuff to seal windows into military grade displays.

Dundee 's your nearest shop.
As long as surfaces ar degreased ( little alcohol ) before application this'll do the job. A little masking tape for where you don'twant it to go.
Have seen after 8 years fielded with the army still working and lookin as new.

And what would that be used on ?

That looks like serious stuff :shock:

Our lad's Warrior and Scimitar vehicles.
This adhesive stands alot of abuse. Also excelent electrical sealant for damaged wires.

[xXBADGERXx]

Don`t they prime them first ? , all the stuff I have had to pot has had to be done in Black as well , but that is on Tanks and they deffo take a hammering

[Shawthing]

Ther are lots of differnt types of 'Rubbers' . Some have catalysts, some need primers.
This doesn't, against glass metals plastics . 24hrs cure aslong as it is not too thickly applied.
Mil Spec rubbers are seriously expensive, so no good for Tread starter. This is a commercialy available material which was qualified for it's specific purpose. As good as the MIL sec stuff i've seen.

[xXBADGERXx]

We tend to mix our own on site or if it is in a tube then we use an approved Mil-Spec sealant
